Abstract

Post-trial injections of norepinephrine (NE) or cycloheximide (CHX) into the amygdala produces a long-term retention deficit (amnesia) for a 1-trial footshock experience in rats. Concomitant post-trial injections of the adrenergic antagonist, propranolol, prevents NE-, but not CHX-induced amnesia. These results indicate separate mechanisms of action for amnesia produced by intracranial CHX and NE injections.
